IMPROVEMENT IN SUGAR-CUTTING MACHINES.

Specication forming part of Letters Patent No. 164,767', dated June 22, 1875; application tiled May 26, 1875.

CASE G.

'of sugar over a table, and between cutting or t clipping tools, a cutting or clipping mechanism by which, with a single pair of cutters, the slabs of sugar held in said carrier can be cut into cubes or blocks while the sugar is' moved in one direction only. rlhe invention is intended as a modification of the improved machine for cutting' sugar into slabs described in another application, marked A, liled by me at the same time with this.

lhe invention consists principally in the application of Va pair of X-shaped clippingtools, arranged respectively above and below the perforated carrier, as hereinafter more fully described.

ln the accompanying drawing7 the letter A represents the frame of the sugar-cutting machine. O is the carrier, perforated to receive a slab of sugar in cachot' its perfbrations, and carry the same within reach of andrbetween the cuttingtools. D D are the cutting-tools or clippers, one being fastened to a cross-bar, b, above the table a ofthe frame A, while the other cross-bar, d, carrying the other cutter, D, is below said table. The two crossbars are parallel with each other, and each of the two knives or cutters D D is in shape of a cross,

or lrter X, so ihat the incisions made by them will also be cross-shaped. The cutting-blades of the upper cutter D are, of course, exactly in line with those of the lower cutter D, and while the slab of sugar passes between the two cutters it is reduced into blocks of the rcquired size by the cutting or clipping action of the knives. The table uis, ofcourse, slotted to allow the lower cutter to reach the sugar that is placed on the table. The upper crossbar b is, by rods e, connected with eccentrics on the rotary'driving-shait E, while the lower cross-bar d rests on cams j' of this `drivingshaft, as shown in Fig. 3. By the action of this driving-shaft E the lower cutter D is moved up at the same time that the upper cutter is moved down, and the sugaris thus clipped on opposite sides, and it is quite evident that, owing to the cross-shaped form of the cutters, a rectangular or nearly rectangu lar slab of sugar must be cut into cubes'when fed by intermittent motion between the said cutters. It will also be observed that by the use ofthe single pair of X-shaped clippers I produce a very simple machine, yet I leave room for play, and do not clamp the sugar, as would be the case if hollow prismatic cutters were employed. A single cross-shaped cutter, D, may also be advantageously used above the stationary table a to cut the sugar, without the use of a lower cutter, D.

I claim as my invention- 1. In a sugar-cutting machine, the combination of a :reciprocating cutter, D, with the intermittentlymovin g carrier O, which is provided with apertures that grasp the edges of l the slabs of sugar to be cut, and with the stationary table u, substantially as `herein shown and described.

2. The combination of the X-shaped cutter D, placed beneath the slotted table a, with the carrier O, and with the upper X-shaped cutter D, all substantially as herein shown and described.

The above description of my invention signed by me this 25th day of May, 1875.
